SNAI1 and breast cancer: To extend the data generated from the Hs578T cell model, we queried all the human breast cancer cell models included in the GOBO database (Fig. 7E) and identified 19 cell lines in which high‐level Snail1 correlated with high BMP6 or, inversely, low‐level Snail1 correlated with low‐level BMP6 (Fig. 7F).
